KARP-3-Flute 50° Helix Corner Radius End Mill for Aluminum
Commodity Brief
Recommended for side milling, slotting and face milling in aluminum alloys and copper; the corner radius forms a specified fillet where the wall meets the floor.
Three flutes, a 50° helix and a 3×D cutting length suit profiles and slots with taller walls. Multiple corner-radius options let the tool match the part’s fillet geometry.
⌀1–16 mm; 55 sizes.
